何谓假小叶?其形态结构如何?

答案

参考答案:

肝硬化时正常的肝小叶结构被破坏,广泛增生的纤维组织将原来的肝小叶分隔,包绕成大小不等、圆形或椭圆形的肝细胞团,称为假小叶。假小叶不同于正常肝小叶,假小叶内肝细胞索排列紊乱,小叶中央静脉缺如、偏位或出现两个以上的中央静脉,有时还可见被包绕进来的汇管区。

     Has your life changed a lot? What will happen in your life in the future? Life in the 21st century will be  different because many changes will take place,but what will the changes be?

     The population is growing fast. There will be more and more people in the world and most of them will live longer than before. Computers will be much smaller and more useful, and there will be at least one in every home. And computer study will be one of the important

subjects in school.

     People will work fewer hours than they did in the  20th century, and they will have more free time for  sports,watching TV and traveling. Traveling will be  much cheaper and easier. And many more people will go to other countries for holidays.

    There will be changes in our food,too. More land  will be used for building new towns and houses. Then  there will be less room for cows and sheep. So meat will  be more expensive. Maybe no one will eat it every day,  instead,they eat more vegetables and fruit. Maybe people

will be healthier.

    Work in the future will be different,too. Dangerous  and hard work will be done by robots. Because of this,  many people will not have enough work to do. This will  be a problem.
